# Electrical Tools You Need While Working On Circuit Based Projects

For professional electricians and hobbyists alike, having the best tools make the actual work experience to be desirable. Just pause for a while and think about what the opposite could be. With the best tools, you don’t have to exert more energy. In other ways, having the best tools will save you time while leading the most productive outcomes.

# Standard Resistor Values

Resistors and Capacitors are types of passive electronic components. The basic unit of resistance is the ohm (Ω) and capacitance is Farad.

Standard base resistor values are given in the following tables for the most commonly used tolerances (1%, 2%, 5%, 10%), along with typically available resistance ranges.

In 1952 the IEC (International Electrotechnical Commission) decided to define the resistance and tolerance values into a norm, to ease the mass manufacturing of resistors. These are referred to as preferred values or E-series, and they are published in standard IEC 60063:1963. These standard values are also valid for other components like capacitors, inductors and Zener diodes. The preferred values for resistors were established in 1952, but the concept of the geometric series was already introduced by army engineer Renard in the 1870s.

# Resistor Color Code Calculator

The electronic color code is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others. A separate code, the 25-pair color code, is used to identify wires in some telecommunications cables.

Standard Resistor and Capacitor values with IEC and EIA code is explained in previous post.

This tool is used to decode information for color banded axial lead resistors. Select their colors to determine the value and tolerance of the resistor.

# ICL7107 Digital Voltmeter

The circuit given here is of digital voltmeter with LED 7-segment display using the ICL7107. It measures voltage from 0.00V to 99.9V. ICL7107 is a 3 1/2 digit A/D converters with LED 7-Segment Driver.

The Intersil ICL7106 and ICL7107 are high performance, low power, 31/2 digit A/D converters. Included are seven segment decoders, display drivers, a reference, and a clock. The ICL7106 is designed to interface with a liquid crystal display (LCD) and includes a multiplexed backplane drive; the ICL7107 will directly drive an instrument size light emitting diode (LED) display.
